PURPOSE:To make it possible to conduct heterochromatic three LED pellets mounting required for full-color emission, to improve color-mixing property, and to prevent generation of foam when molding. CONSTITUTION:A double molded structure is formed by molding the recessed part of an inner container 2 using the resin having a high concentration dispersant and the entire inner container 2 is molded by the resin having low concentration dispersant. Also, in the case of single molding, a notch is provided on the inner container 2 so that foam is bled out excellently. As a result, at least three LED pellets can be mounted on the recessed part of the inner container, and color-mixing property can be improved by the double molding structure. |
